Detailed Description

Currently when you plug a USB graphics adapter into a system, nothing interesting occurs. These USB devices are being used in more docks and systems going forward. We need to provide a better experience for users.

Benefit to Fedora

Proper support for a current technology.


Re-write the X server to support GPU hotplugging. - done

Port drivers to new X server interfaces. - done

Write a KMS driver for displaylink devices. - done

Write a generic KMS driver with hotplug support. - done

Implement some DE support for it. - TODO (optional).

How To Test

Own the USB displaylink hardware. Plug it in, see if the desktop expands or if you can control the desktop via the gnome panels.

User Experience

Just works.



Contingency Plan

Do nothing.



Release Notes
